yup, no tow charge for me (red neck town, everyone has a truck and a rope and the cops do not care) but I am watching it very close.

well, took it to the shop that installed the fuel pump and they called me and said they couldn't get the car to react like I had described. I went over to the shop and drove the car myself with the mechanic in it. yup, you guessed it. the car fixed its self. no more problems. grr, I hate that. I feel like I am just waiting for the other shoe to drop. I have put 50 miles on it since and no issues. guess I will drive it until it cacks. grrrr

The pump is a module, in short, a cup that holds maybe close to a quart of fuel right around the pump inlet to let car stay running when fuel is sloshing around everywhere but the correct spot as fuel runs low in tank. The pump refills the cup on the run as part of the output is bypassed, when pump efficiency drops off after it cannot pull in fuel fast enough because filter is clogged, then the cup itself starts running dry, it just happens to show up turning right first. Eventually it will get worse and worse, to finally stalling with no re-startup after simply turning right slowly out into street from say parking lot.

Modern in tank fuel pumps work great but burn up quickly if they are allowed to run dry intermittently like when tank fuel level gets low. The cure was to put pump in a module that very rarely runs dry if working as designed. The reason why now all owner's manuals stress to never run out of fuel, it can damage the pump, they are fuel cooled. Running ethanol in fuel made for many new problems though, it carries garbage that commonly clogs in-tank filters, especially on earlier models of these.

sigh. fuel pump time again. thank you so much for your expertise.

i dont know know WHY it does that but i experienced those symptoms of a bad fuel pump first hand. the car would completely die in long and hard right handers and it would stutter horribly at higher revs. but otherwise it would idle and drive fine so long as you just went along like you are driving miss daisy.

whynotthinkwhynot >> I am just curious. Why/how would a fuel pump be linked to 'cutting out on long right hand curves'. I am thinking in terms of inertia and time. Is the fuel running away from the pump? Why is that in issue with the pump? Can you explain what is happening?
Thanks!!

If it is bypassed, there is a chance that the fuel pump will continue to run after an accident, and if the fuel line is broken fuel will be pumped out at 60 gpm and could catch fire or explode.[/QUOTE]

yea, that would be bad. ok I will try this. I paid someone to put in the fuel pump. I can go back to them and get it looked at. thanks for the information.
